Real cost ranges for Hong Kong SAR, priced in HKD. Every row is what homeowners actually spend across the scope spectrum — the low end is a pull-and-replace on the existing footprint, the high end is a full custom build with premium finishes.

Cabinets, counters, appliances, and plumbing/electrical updates drive the range. The top of the band reflects full layout changes and premium finishes; the bottom holds for pull-and-replace scopes on the existing footprint.

Scope yours with Baily in Hong Kong就香港的裝修工程向Baily諮詢，您不會接到十二通來自不同承建商的電話。香港是全球住宅密度最高的城市之一，其獨特的市場結構讓「一對多」的轉介模式更顯得低效。中環與半山的豪宅大廈、山頂獨立屋、淺水灣的海景洋房、跑馬地的低密度住宅、跆大坑的新舊並存區、尖沙咀的服務式公寓、九龍塘的花園洋房、以及西貢與愉景灣的離島住宅，每一類物件涉及的屋宇署（Buildings Department）審批、註冊認可人士（Authorized Person）介入程度、以及業主立案法團或公契（Deed of Mutual Covenant）規範都大相徑庭。Baily會先掌握這些在地脈絡，再為您介紹一家在BD承建商註冊制度下登記有案、並熟悉您大廈公契與管理處要求的承建商。目前市場上如HomeKon、Oneday等聚合平台會將一件諮詢發送給多家廠商；Baily堅持「一位屋主，一家廠商」的原則。香港的颱風強度、滑坡風險、以及極高密度的共用結構，使得您的工程必須交由熟悉《建築物條例》、屋宇署認可承建商名冊、以及斜坡維修作業守則的專業團隊。這就是我們的服務承諾。
